WlN-DVHLL. AND PUMP COUPLlNG.

SPECIFICATION forming part of Letters Patent No. 670,238, dated March 19, 1901.

Application filed September 28| 1900. Serial No. 31.347. (No model.)

To all whom, it 'nm/7j concern:

Be it known that I, EMERY F. KINGSTON, a citizen of the United States, residing at Hastings, in the county of Dakota and State of Minnesota, have invented certain new and useful Improvements in Windmill and Pump Couplings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to provide an improved coupling for connecting and disconnecting -the reciprocating stock of a windmill to the piston-rod of a pump.

To the end above indicated -the invention consists of the novel devices and combinations of devices hereinafterdescribed, and deiined in the claim.

The invention is illustrated in the accompanying drawings, wherein like charactersindicate like parts throughout both views.

Figure 1 is a View in side elevation with some parts broken away and others sectioned,

showing a portion of a windmill-stock and of a pump-rod and illustrating my improved coupling applied thereto; and Fig. 2 isa horizontal section on the line x2 co2 of Fig. 1.

The numeral 1 indicates the reciprocating stem of the windmill, and the numeral 2 indicates the pump-rod or piston-stern of the pump. A pair of metal strapsand 4 are secured by nutted bolts 5 to the windmill-stem 1. The strap 4. is formed with ahead 6, which has a vertical passage 7, through which the' pump-rod 2 works loosely. Said head 6 has also a sleeve extension 8, through which and a plunger-seat 9, formed therein, a lock-bolt or plunger 10 is mounted to work for engagement and disengagement with a perforation 11 in the pump-rod 2. The strap 4 has a head 12, the base of which bears directly against the extended end of the sleeve 8. A coiled spring 13 on the stem portion of the bolt or plunger 10 is compressed between a shoulder 14 of said bolt and the base of the flanged strap-head l2. This spring 13 puts the lockbolt or plunger 10 under strain to enter through the perforation 11 of the pump-rod 2, as shown in Fig. 1.

The numeral 15 indicates a handpiece,

which, as shown, is pronged at its butt or inner end, so that it embraces the adjacent projected end of the lock-bolt 10, being pivoted thereto, as indicated at 16. The butt or inner end of the handpiece 15 has two bearingsurfaces 17 and 18, that extend approximately at right angles to each other and are adapted in turn to engage with the base and between the side flanges of the pronged strap-head 12. The bearing-surface 17 extends very much closer to the pivot 16 than does the bearingsurface 18. More definitely stated, the bearing-surface 17 extends so close to the said pivot 16 that when the handpiece 15 is turned into the position indicated by full linesin Fig. 1 the lock-bolt or plunger 10 will he permitted under the action of the spring 13 to be thrown into its operati ve position. On the other hand, the bearing-surface 18 extends at such a distance from the pivot 16 that when the handpiece 15 is turned into a position indicated by dotted lines in Fig. 1 the said lock- 'oolt or plunger will be drawn and held inward in an inoperative position, in which p0- sition it is entirely withdrawn from the vertical passage 7, in which the pump-rod 2 at such time is free to move.

When it is desired to connect the windmillstern with the pump-rod, it is only necessary to move the handpiece 15 from its dotted-line position and toward or to the position indicated by full lines in said Fig. 1. The coupling will then take place automatically whenever the windmill-stem or the pump-rod is moved so as to bring the perforations 9 and 11 into registration.

The convenience of this device will be readily appreciated by all persons familiar with windmills, and it is important to note that there are no loose parts which may become displaced or lost.

It will of course be understood that the do- Vice illustrated in the drawings is capable of considerable modification within the scope of my invention.

What I claim, and desire to secure by Letters Patent of the United States, is as follows:

The combination with a reciprocating Windmill-stem and the piston-rod of a pump, of a spring-pressed lock-bolt carried by one of said members and engageable with the other IOO to lock the parts together, there being e Het bearing-Surface on the inem bei` which Carries seid lock-bolt, and a handpieoe pivoted to said lock-bolt, which handpieee is provided with fiat bearing-surfaces 17 and 1S extending approximately at L rigl'lt angle to eeeh other and cooperating with seid bearing-surface, the former permitting said look-bolt to beeoine operative and the latter holding the Same inoperative, substantially as described. Io

In testimony whereof I MEX my signature in presence of two witnesses.
